El Ciclo Menstrual: Lo Que Pasa en Tu Cuerpo

Imaginate que tu cuerpo es como una casa que se prepara cada mes para recibir un huésped muy especial. La menstruación es lo que pasa cuando ese huésped no llega y la casa necesita limpiarse para empezar de nuevo.

Cuando el óvocito secundario (básicamente un óvulo maduro) no es fecundado, se seca y sale del cuerpo aproximadamente dos semanas después. Es como cuando una flor no es polinizada y simplemente se marchita.

El flujo menstrual está compuesto por sangre y tejidos del revestimiento interno del útero, llamado endometrio. Este proceso normalmente dura de 3 a 5 días, aunque puede variar en cada persona.

¡Dato curioso! El síndrome premenstrual puede incluir síntomas como acné, sensibilidad en los senos, cambios de humor, hinchazón, dolores de cabeza, irritabilidad, cansancio y antojos de comida. ¡Es completamente normal!

Tres hormonas clave controlan todo este proceso: la hormona luteinizante (que desencadena la ovulación), la hormona folículo estimulante (que ayuda a desarrollar los óvulos), y el estrógeno (que regula todo el ciclo). Estas hormonas trabajan juntas como un equipo perfectamente coordinado.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

El ciclo menstrual es un proceso natural que ocurre cada mes en el cuerpo femenino para prepararlo para un posible embarazo. Cuando esto no sucede, el cuerpo se "reinicia" a través de la menstruación.
